BackgroundThis review aims to assess the effect of oral administration of probiotics and/or prebiotics in children and women of reproductive age (WRA) to improve intestinal iron absorption, hemoglobin, and ferritin levels.MethodsRandomized controlled trials from published literature on probiotics and or prebiotics for prevention or treatment of anemia as a supplement or fortification in children or WRA till Jan 31, 2023, were included. Studies on probiotics and prebiotics in patients with anemia due to other causes were excluded. Screening and data extraction was done using Distiller SR and meta-analysis was performed using Revman 5.4.1.ResultsA total of 1925 records were identified from Pubmed, Embase, and Cochrane, of which 29 were included in the systematic review (14 supplementation and 15 fortification studies; 15 studies in children and 14 studies in WRA). The major interventions included galacto-oligosaccharide, inulin, heat-killed H61, Lactobacillus plantarum 299v, Lactobacillus reuteri, Lactobacillus acidophilus. Meta-analysis of 5 studies in WRA showed that the use of prebiotics and/or probiotics with or without iron was associated with little or no effect on hemoglobin. However, there is low certainty of evidence that the intervention led to improvement in fractional absorption of iron as compared to placebo or iron [8 studies, n = 335, mean increase 0.74%, 95%CI-0.11-1.38, p = 0.02]. Meta-analysis of 6 studies in WRA using prebiotics and/or probiotics with or without iron led to a significant increase in ferritin levels in WRA (mean increase 2.45 ng/ml, 95% CI 0.61-4.3, p = 0.009, n = 320) [Moderate certainty of evidence]. In children, meta-analysis of up to 8 studies did not result in any significant change in hemoglobin, ferritin and fractional iron absorption [low or very low certainty of evidence].ConclusionThere is some evidence to show that the use of prebiotics or probiotics (especially Lp299v and GOS) with or without oral iron can improve iron absorption in women and lead to improvement in ferritin levels in women. However, the current evidence does not conclusively show the benefit of these interventions in improving hemoglobin levels in women and children.

BackgroundPatients with a low serum blood hemoglobin concentration suffer from a pathologic state that contributes significantly to morbidity and mortality figures worldwide. Oral iron supplementation, the most common method of treatment, is reported to have poor patient adherence, due to its unwanted side effects. Lactoferrin is a globular glycoprotein of the transferrin family that has shown promising results in patients with a low hemoglobin profile. This systematic review and meta-analysis of randomized clinical trials explore its effect on blood hemoglobin compared to conventional iron preparations.MethodsWe followed the PRISMA Guidelines for reporting systematic reviews and meta-analyses. A systematic search was conducted in electronic databases (PubMed, CINAHL, Scopus, and Cochrane) from inception to June 2022. Meta-analysis was performed on studies where the primary outcome was the mean Hb concentration, comparing lactoferrin to ferrous sulfate subgroups. We assessed the methodological quality of the trials using the Jadad scoring scale.ResultsNineteen trials published between 2006 and 2022 met the eligibility criteria. It has been found that the levels of Hb concentration in different populations with varying health conditions undergo a moderate to significant change after treatment with all types of trialed interventions, including both iron and lactoferrin treatment, in both the intervention group and the comparison group. Most of the studies report that LF showed a statistically significant increase in Hb concentration levels, compared to those in the iron group. The meta-analysis included seven trials comparing the effectiveness of lactoferrin to ferrous sulfate for patients with low Hb concentration. The analysis showed a statistically significant increase in Hb levels in the oral bovine lactoferrin group compared to ferrous sulfate (SMD -0.81, 95% CI: -1.21, -0.42, p 2 = 95.8%, P heterogeneity ConclusionsLactoferrin is an effective intervention at doses of 100-250 ng/day, for patients with a low Hb concentration. As a safer option and with high compliance evidence, lactoferrin can serve as an iron replacement treatment for patients who may be experiencing adverse side effects due to iron intake.

Nutritional deficiencies are prevalent in populations across the world. Fortification of staple foods has been used as an alternative to supplementation to address many deficiencies. One such staple is salt, which has long been fortified with iodine, but more recently with iron, folate, and other micronutrients. Our objective was to determine the effects of fortified salt on nutritional and health outcomes among children, adolescents, and adults. We conducted a systematic review of published and unpublished literature using a pre-defined search strategy. Abstracts and full texts were screened for randomized trials, quasi-randomized trials, and pre-post-designs of double or multiple fortified salt. We calculated the weighted pooled effect sizes for the effects of fortified salt on nutritional and health outcomes. Of the 395 studies identified, 33 (including 37 intervention-control comparisons) fit our inclusion criteria. Of these comparisons, 26 studied the effects of salt fortified with iron and iodine [double fortified salt (DFS)], 2 studied the effects of salt fortified with folic acid and iodine, 1 studied the effect of triple fortified salt, 1 studied the effect of quadruple fortified salt, and 7 studied the effects of multiple micronutrient fortified salt (MMFS; fortified with ≥5 nutrients). Pooled effect sizes indicated positive effects from all iron-containing fortified salt on hemoglobin concentration [standardized mean difference (95% confidence interval): DFS 0.36 (0.22, 0.50), n comparisons = 26; triple fortified salt 1.56 (1.42, 1.70), n comparisons = 1; quadruple fortified salt 0.33 (0.02, 0.63), n comparisons = 1; MMFS 0.23 (0.03, 0.43), n comparisons = 6]. DFS and MMFS reduced the odds of anemia and iron deficiency (ID) anemia. MMFS improved serum folate and reduced the odds of ID. Pooled effects on biomarkers of vitamin B12, vitamin A, and zinc status varied by type of salt, but were largely not significant. Fortification of salt with iodine and iron, with and without other nutrients, is effective in increasing hemoglobin and reducing the odds of anemia and ID in population-based studies.

Background: Community pharmacist-led interventions are effective in improving health outcomes; however, their impact in improving preconception and pregnancy health is not clear. This study evaluated the effectiveness of community pharmacist-led interventions which aimed to improve health outcomes of preconception and pregnant women. Methods: A systematic review of the literature, consistent with PRISMA guidelines, was performed. Five electronic databases were searched up to February 2021. Results: Four studies, three in pregnant women and one in preconception women, were identified. The studies focused on improving micronutrient status and smoking cessation. The studies increased knowledge about, and use of, iron supplements, and improved iron status and smoking cessation rates in pregnant women, while improving knowledge regarding, and increasing the use of, preconception folic acid. The studies were ranked as weak to moderate quality. Conclusion: This review provides preliminary evidence for the potential benefit of community pharmacist-led interventions to improve the health of women before and during pregnancy.

BackgroundThe UN Sustainable Development Goal aims at a 50% reduction of anemia in women of reproductive age (WRA) by 2030. Several nutrition-specific and sensitive interventions are targeted across low- and middle-income countries (LMICs) to reduce anemia.ObjectivesIn this meta-review we comprehensively assessed the effectiveness of nutrition-specific and -sensitive interventions on hemoglobin (Hb) and serum ferritin (SF) concentrations and the prevalence of iron deficiency and anemia among WRA, pregnant women, and lactating women from LMICs.MethodThe preparation of the present meta-review followed a double-blinded synthesis process with 3 stages: screening, quality appraisal, and data extraction in Eppi Reviewer. A comprehensive search was performed for systematic reviews (SRs) published between January 2000 and May 2022 using 21 international, national, and regional databases. The methodological quality appraisal of included studies was conducted using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) checklist.ResultsA total of 23 SRs evaluated the effects of various nutrition-specific interventions included in the final synthesis. The included SRs included analyses of nutrition-specific interventions such as supplementation of the nutrients iron (n = 7), iron and folic acid (n = 4), vitamin A (n = 3), calcium (n = 2), multiple micronutrients (n = 7), and intravenous iron sucrose (n = 2). Also, SRs on fortification of nutrients included multiple micronutrients (n = 6), iron and folic acid (n = 4), and iron (n = 4). Of the 23 SRs, 22 were of high quality. Iron with or without folic acid supplementation and fortification and vitamin A supplementation consistently showed positive effects on either reduction in the prevalence of anemia or iron deficiency and improving the Hb or SF concentrations in WRA and pregnant women from LMICs.ConclusionThe comprehensive meta-review reported the beneficial effects of iron with or without folic acid, multiple micronutrient supplementation/fortification, and vitamin A supplementation in reducing the prevalence of anemia or iron deficiency and increasing Hb or SF concentrations in WRA from LMICs.

BackgroundThe Cambodian Ministry of Health is exploring transitioning from iron and folic acid (IFA) to multiple micronutrient supplements (MMS) during pregnancy and is seeking rigorous evidence to inform this policy change.ObjectiveWe aimed to assess the adherence and acceptability of MMS compared with IFA supplementation during pregnancy.MethodsWe conducted an open-label cluster-randomized noninferiority trial across 48 health centers in Cambodia. A total of 1546 healthy pregnant individuals (18-45 y) were recruited at their first antenatal care (ANC) visit (ResultsOverall, 88% of participants completed the trial, with high mean adherence rates across arms (91% for IFA-90, 95% for MMS-180, and 95% for MMS-90). The adjusted mean (95% CI) difference in adherence rates between MMS-180 and IFA-90 groups was 3.9% (1.7, 6.2). The adjusted mean (95% CI) difference in ANC visits for MMS-180 and MMS-90 groups was 0.0 (-0.1, 0.2) visits. The acceptability of MMS was positive (90%-100% "agreement" across 6 domains).ConclusionsBoth IFA and MMS were highly acceptable, yet adherence to MMS was superior to IFA. These findings support the transition from IFA to MMS in Cambodia. This trial was registered at Clinicaltrials.gov as NCT05867836.
